Cerberus ADSL2+ Wi-Fi (P 6331-5) QoS Quality of service allows network administrators to configure the routers to meet the real time requirements for voice and video. Different networks use different QoS markings like: • ToS network: ToS bits in the IP header • VLAN network: priority bits in the VLAN header • DSCP network: uses only 5 bits of the CoS • WLAN: WLAN QoS header. The QoS framework is supported on all the above domains.
Cerberus ADSL2+ Wi-Fi (P 6331-5) QoS / Egress For packets going out of the router, the markings (CoS) need to be translated to the mappings understood by the network domains. The reverse CoS and domain mapping is configured using the Egress. There are three Egress modes: • No Egress Mode The default Egress page setting for all interfaces is No Egress. In this mode, the domain mappings of the packets are untouched.
Cerberus ADSL2+ Wi-Fi (P 6331-5) Interface – Select the WAN interface to configure the QoS for outgoing packets; LAN interface cannot be selected as VLAN is currently supported on the WAN side only. Unclassified Packet – Some locally generated packets might not have been classified and thus do not have a CoS value, such as PPP control packet and ARP packet.
Cerberus ADSL2+ Wi-Fi (P 6331-5) QoS / Ingress Ingress enables you to configure QoS for packets as soon as they come into the router. The domain mappings are converted to CoS (the common language) so that the priority marking is carried over. There are four Ingress modes: • Untrusted Mode Untrusted is the default Ingress page setting for all interfaces. In this mode, no domain mapping is honored in the router. All packets are treated as CoS6 (best effort).
Cerberus ADSL2+ Wi-Fi (P 6331-5) Interface – Select the WAN interface here to configure the CoS for incoming traffic. Only WAN interface can be selected as VLAN is currently supported only on the WAN side. Class of Service – The selections are (in the order of descending priority): CoS1, CoS2, CoS3, CoS4, CoS5, and CoS6. User Priority – The selections are 0, 1, 2, 3, 4, 5, 6, 7. Notes: • Any priority bits that have not been mapped to a CoS default to CoS6, the lowest priority.
Cerberus ADSL2+ Wi-Fi (P 6331-5) • Static The Ingress - Static page enables you to configure a static CoS for all packets received on a WAN or LAN interface. Interface – Select the interface here to configure the CoS for incoming traffic. Class of Service – The selections are (in the order of descending priority): CoS1, CoS2, CoS3, CoS4, CoS5, and CoS6.

HTB Queue Discipline – The hierarchical token bucket queue discipline is a rate-based shaping algorithm. This algorithm rate shapes the traffic of a class over a specific interface. All CoSx traffic uses a specific rate to which data will be shaped.
Cerberus ADSL2+ Wi-Fi (P 6331-5) Protocol – The selections are TCP, UDP, ICMP, Specify, and none. If you choose Specify, you need to enter the protocol number in the box next to the Protocol field. This field cannot be configured alone, additional fields like IP, Source MAC, and/or Ingress Interface should be configured. This field is also required if the source port or destination port has been entered. Source Port – The source protocol port.
Cerberus ADSL2+ Wi-Fi (P 6331-5) Routing / Static Routing If the router is connected to more than one network, you may need to set up a static route between them. A static route is a pre-defined pathway that network information must travel to reach a specific host or network. You can use static routing to allow different IP domain users to access the Internet through the router. The New Destination IP is the address of the remote LAN network or host to which you want to assign a static route.
Cerberus ADSL2+ Wi-Fi (P 6331-5) Routing / Dynamic Routing Dynamic Routing allows the router to automatically adjust to physical changes in the network. The router, using the RIP protocol, determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network. The Direction determines the direction that RIP routes will be updated.
